Reading Anthropic’s guest post on Fable 5.1 inside Claude Science: planar N=4 SYM nine-loop hexagon amplitudes via an explicit science harness and minimal human intervention—harness × agent-loop, not a bigger-model story.

Anthropic says Claude found ART (array-associated reverse transcriptases) under high-level direction. This post cross-checks the news post and technical report: search discovery vs unknown function, reproducibility limits, research-agent pipelines, and how builders should read the story.
